Laminated Safety Glass
Laminated safety glass is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyral (PVB), between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. This produces a characteristic “spider web” cracking pattern when the impact is not enough to completely pierce the glass.
Where to use laminated glass?
- structural glazing
- show-window glazing of important objects
- sidewall support panels of stair spans and escalators
- balcony glazing
- glass floors and stages of stairways
- component parts of furniture and glass table-tops
- all kinds of outside glass fencing
- Glazing of the buildings located in a noise impact area of airports
- bullet-proof glass
- ceiling glazing
- glazing of premises and room of banks
Protection from vandalism and burglary
- Laminate resists penetration – glass may break but interlayer retains overall integrity and continues to act as a barrier.
- Protects against break-ins by preventing or slowing down burglary attempts.
- Protects against vandalism and brief attacks using easily available objects.
- Withstands repeated blows from heavy objects such as bricks, hammers, crowbars and similar hand held heavy objects.
- Depending on the extent of the attack the product remains integral and protects the premises adequately and limits penetration whilst awaiting replacement, offering: – protection from secondary looting – damage from the wind and weather – safety while broken, reducing personal injury – often no need for ‘boarding up’
- Typical applications include buildings or shops displaying valuable goods, banks, building societies, post offices, security glazing in hospitals and prisons, museum display cases etc.
- Available in 7.5 to 19.5mm standard thicknesses.
- The correct grade and thickness specified for the application depends on the value of goods on display, degree of risk, estimated time needed by thieves to break in and enter.
- Conforms to BS 6206: 1981 Class A.
Toughened Safety Glass is up to five times stronger than ordinary glass of the same thickness. Because of its increased strength, toughened glass allows architects and builders far greater scope in their use of glass in buildings. It meets world-wide safety standards for glass subjected to accidental human impact at the highest level of severity. Wherever the benefits of ordinary glass need to be combined with extra strength, safety or heat resistance, toughened glass can offer a complete and proven solution. Toughened glass is advantageous, such as structural applications, barriers and roof glazing. Toughened glass is manufactured by subjecting final size, edgeworked panes of glass to a heating and cooling treatment whereby high compressive stresses are set up at the surfaces with balancing tensile stresses in the centre. The high compressive surface stresses give the toughened glass its increased strength.
- Based on over 60 years of worldwide manufacturing experience.
- Up to 5 times stronger than ordinary glass of the same thickness.
- Conforms to the requirements of BS 6206: 1981 Class A as well as European Standard BS EN 12600 and many worldwide safety standards.
- Ideal for use in countless applications, from windows to barriers, interior design, curtain walling etc.
- When broken, toughened glass shatters into small, blunt-edged fragments which reduce the risk of personal injury.
